VEHICLE-SPRING.

SPECIFICATION forming part of Letters Patent No. 488,795, dated December27, 1892. Application filed August 25, 1892. Serial No. 444,121. (Nomodel.)

To all whom it may concern.-

Be it known that I, J OHN MOPARTLAND, a citizen of the United States ofAmerica, residing at Wakefield, in the county of Washington and State ofRhode Island, have invented certain new and useful Improvements inVehicle-Springs, of which the following is a specification, referencebeing had therein to the accompanying drawings.

This invention relates to improvements in springs for vehicles.

The object of this invention is to providea spring of such peculiarconstructi0n,whereby the strain of the load shall be effectuallyequalized; furthermore, one that will load level and at the same time belight and of few parts; furthermore, the invention contemplates theprovision of a spring that shall be strong, durable and comparativelyinexpensive of manufacture.

With these objects in view, the invention consists in a wagon springproper, having centrally thereof bent up V, or W, portions meeting atthe center of the wagon body where they are secured to the undersidethereof by suitable supporting brackets, the extreme ends of said springbeing pivotally mounted in spring clips secured to the running gear;furthermore, the combination with the side springs as described, of thetransverse springs pivotally secured at their ends to said side springs,preventing spreading of the latter and at the same time being adapted toco-operate therewith to facilitate an even motion of the vehicle, andbent up centrally in the form of an S, where they are again secured tothe wagon body by suitable shackles.

Furthermore, the invention consists in Various novel details ofconstruction, hereinafter to be more fully described and specificallypointed out in the claims.

In describing my invention in detail, reference is had to theaccompanying drawings, forming a part of this specification, whereinlike letters of reference indicate similar parts in the several views,in which,

Figure 1, is a top plan view of the improved spring, shown attached tothe running gear of a vehicle. Figs. 2, 3, 4t and 5, are detail views ofthe supporting clips, brackets &c.

Fig. 6, is a View in form of side spring.

In the drawings A, indicates the side springs having formed centrallythereof inwardly bent V-shaped portions a, meeting at the center of thewagon body and secured firmly thereto by the double supporting bracketor shackle a and loosely in the single shackle a The extreme ends of theside springs being pivotally secured to the running gear by shackles aand the spring clips a the latter being formed with apertured lugs a",integral as shown in Fig. 3, or as shown in Fig. 2, wherein the bridgepiece a connecting said lugs has a recess a, formed on the under sidethereof adapted for the reception of the branch arm a", of the clip anda screw a securing the samein position. At intermediate points betweenthe center and ends of the side springs, transverse springs D, arearranged by a pivotal connection at the ends thereof, in clips orshackles b, of the said side springs and are formed at the center withbent-up S- shaped portions 19 which are secured against the under sideof the body by the supporting brackets 5 These transverse springs serveto brace and retain the side springs in proper position at the same timepreventing a spreading of the latter, and co-operating with the same tofacilitate an even motion of the vehiole.

It will be readily understood that the spring clips may be cast integralwith the rear axle or removably secured thereto as shown; furthermore,that if desired, the side springs may be used separately, that is to saywithout the transverse spring; furthermore, that various changes may bemade in the detail construction and proportion withoutmateriallydeparting from the general idea involved.

Having fully described my invention, what I claim and desire to secureby Letters Patent is:

1. In a spring for vehicles, comprising the side springs having inwardlybent portions suitably secured to the wagon body, the spring clipssupporting the rear ends of said springs and the shackles connecting theforward ends thereof to the running gear, substantially as specified.

2. In a spring for vehicles comprising the perspective of a modifiedside springs having inwardly bent portions supported from the undersideof the wagon body at a point approximately the center thereof, suitablespring clips on the rear axle supporting the rear ends of said springs,the opposite ends being connected by shackles to the front bolster andthe supporting brackets a substantially as specified.

3. In a spring for vehicles, comprising the side springs havingcentrally thereof inwardly bent portions secured to the wagon body, thespring clips a supporting the rear ends of said springs as described,the shackles a supporting the forward ends thereof, and the supports a asubstantially as described.

4. In a spring for vehicles, the combination with the side springs ofthe transverse springs having formed centrally thereof S-shaped portionsand the supporting brackets or shackles for securiu g said S-shapedportions at or near the center thereof, substantially as shown and forthe purpose set forth.

5. The combination with the side springs havingformed centrally thereofinwardly bent portions secured at a point approximately at the center ofthe wagon body and loosely supported in brackets adjacent to the sidethereof, the extreme ends of said springs being pivotally secured to therunning gearby the spring clips a and the transverse springs havingtheir ends pivotally secured to the side springs and at or near thecenter thereof to the wagon body, substantially as shown and described.

(5. In a vehicle spring, the combination with the side springs havinginwardly bent V-portions supported as described, of the transversesprings supported from said side springs and bent up centrally to forman approximate S, substantially as specified.

In testimony whereof I affix my signature in presence of two witnesses.

J OIIN MOPARTLAND.
